Abstract
The present invention provides a polarizer. The polarizer comprises a first membrane having a first polarization region comprising a first plurality of membrane perforations; a second membrane having a second polarization region comprising a second plurality of membrane perforations; and a support structure to which the first and second membranes are attached, the support structure allowing a relative movement of the first membrane with respect to the second membrane, the relative movement enabling an at least partial overlap of one or more membrane perforations in the first plurality of perforations with one or more membrane perforations in the second plurality of perforations in a direction normal to the first polarization region or normal to the second polarization region, resulting in corresponding one or more openings in said direction.
